2.0 Warnings
Disconnect all power
sources
Electricity can be very dangerous.
Installation should be performed only
by a licensed electrician or qualified
personnel.
Battery and wiring safety
Observe all safety precautions of the
battery manufacturer when handling
or working around batteries. When
charging, batteries produce
hydrogen gas, which is highly
explosive.
Wiring connections
Ensure all connections are tight and
secure. Loose connections may
generate sparks and heat. Be sure
to check connections one week after
installation to ensure they are still
tight.
Work safely
Wear protective eyewear and
appropriate clothing during
installation. Use extreme caution
when working with electricity and
when handling and working around
batteries.
Observe correct polarity
Reverse polarity of the battery
terminals will cause the regulator to
give a warning tone. Reverse
connection of the array will not
cause an alarm but the controller will
not function. Failure to correct this
fault could damage the regulator.
Do not exceed the GP-PWM-
25 Amp current and max
voltage ratings
The current rating of the solar
system is the sum of the Maximum
Power Current (Imp) of the solar PV
strings in parallel. The resulting
system Imp current is not to exceed
25 A. The voltage of the array is the
rated open circuit voltage (Voc) of
the PV array and is not to exceed 56
V. If your solar system exceeds
these ratings, contact your dealer for
a suitable regulator alternative.
